Alright well I re-did everything. I even took the script and put just the script on my server only change the constants so it went to the database correctly and I end up with my original problem I got from the get go and that's the registration FAILED... I'm about to just give up or pay someone.
Then after getting the registration failed I changed in sessions.php
When that's changed the registration works. BUT when I login, the username is NOT found. And again I am using the original script, not even using my site, just the script on my server and it's not working "out the box" like everythone says. I should only have to change constants.php in order for it to work right? Just the database stuff right?
